HARROW.

To all whom it may concern.

' particularly to a device of this general character, especially designed and adapted for use as an attachment for a cultivator and it is an object of the invention to provide a harrow of this general character having novel and improved means whereby it may be readilv and effectively secured in applied position.

It is a further object of the invention to provide a novel and improved harrow of this general character including means whereby it may be adjusted to varying widths in accordance with the requirements of the practice.

The invention consists in the details of construction and in the combination and arrangement of the several parts whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein Figure l is a perspective view of a barrow constructed in accordance with my invention; Fig. 2 is an enlarged horizontal section taken on the line 22 of Fig. 1; and Fig. 3 is a detail elevation of one of the toothed clamping plates.

As herein disclosed, 11 denotes the side beams of my improved harrow, having their forward extremities pivotally connected, as at 2, whereby a relative adjustment of said side beams may be had in order to meet the requirements of practice and operatively engaged with each of said side beams are the teeth 3, preferably of the well known diamond type. These teeth are removably and adjustably secured upon the beams of Specification of Letters Patent.

Application filed August 21, 1915. Serial No. 46,696.

the harrowby means of clamping plates, indicated at 12. This plate is provided in its inner face with the groove or channel 13 to receive the teeth 3, and in one end of the plate, a serles of notches or recesses 14 are formed. Adjacent'to the other end of said plate, a transversely disposed opening 15 is provided.

16 designates a U-shaped clamping bolt WhlCll is'adapted to be engaged through spaced openings in the beam 1, one of said openings coinciding with the opening 15 in the clamping plate. Through these coincidlng openings, one of the arms of the U- shaped bolt is engaged, while the other arm 1s seated in one ofthe notches 14 in the end of the clamping plate and disposed through the other opening in the beam. Suitable nuts 17 are threaded upon the ends of the i bolt arms. It will be readily understood that the clamping plate may be easily and quickly adjusted upon the beam by engag-' ing the arm of the bolt in the desired recess 14 so as to position the harrow tooth at an angle with respect to the cultivator beam.

Each of the side beams at a predetermined point intermediate its length, is provided with the inwardly disposed plate or arm 4. The plates or arms 4 are in overlying relatlon and are provided with the longitudinally spaced openings 5, adapted to register and through which the-clamping bolt 6 is directed, in order to maintain the side beams 1 in their various relative adjustments.

7 denotes an upstanding member of predetermined dimensions having its lower extremity provided with the rearwardly disposed extension 8 adapted to be engaged'by the clamping bolt 6, while the upper extremity of said member is adapted to be clamped in any desired manner to the frame of a cul tivator. As the cultivator may be of any type desired, it i thought that an illustration or description thereof is unnecessary. Intermediate its length the member 7 is provided with the forwardly disposed and downwardly inclined bar 9 having its lower or free extremity provided with a lateral extension 10, through which is dispcsed the pivoting member 2, whereby it will be perceived that the member 7 is effectively braced in applied position. I also find it of advantage to suitably secure to the extension 10. a chain 11 or other flexible member which is adapted to be suitably secured to without material departure frorn'theprin the cultivator, whereby the member 7' is'relievedo'fi certain extent of the operating strain.

From the foregoing description, it is thought to be obvious that a harrow for attachment to a cultivator constructed in 5122- cordance with my invention, is of an extremely simple and comparatively inexpensive nature and is particularly welladapted for use by reason of the convenience andfacility, with which it may be assembled, and itjwill also be obvious'that my invention is susceptible of some change and modification 7 comprising two side beams, having adja cent extremities pivotall'y connectedy inwardly disposed arms carried by the side beams and arranged in overlying relation,

said arms being provided with longitudinally spaced openingsadapted to register, a clamping bolt disposed through said openings, an upstanding-member having its lower extremity-- operativel-y engaged with the clamping bolt, and a brace bar projecting.

forwardly. fromithe upstanding member and operatively engaged with the pivotal connectio-n between the sidebeams'.

2. A harrow of the character described comprising two side beams, havingjatlja' cent extremities pivotally connected, in-

.wardly disposed arms carried by the side beams and arranged in overlyingrelation, said arms being. provided w th. longitudlnally spacecl openlngs adapted to register,

clamping bolt disposed through said openngs, an upstanding member having its lower extremity operatively I engaged with the clarnpingbolt, a brace bar projecting for, wardly from the upstanding member and op'eratively' engaged with the pivotal connection betweenfthe side beams, and aflexible' memberloperatively engage d with thebrace bar} V In testimony whereof Ihereunto affix my signature in the presence of two witnesses.-
